Specification of Letters Patent.

Application filed February 3, 1909. Serial No. 475,768.

'1'0 all whom it may concern Be it 'known that I, \VrLLL-iii A. 'LUR- navxu. a citizen of the "United States, andadapted to a system in which the voltage' on a work circuit is regulated and the work circuit is supplied from a source of variable electrtmiotive force.

One object of my: invention is to provide asystem andarrangement by which the voltage applied to the consumption circuit may be automatically regulated in such a manner that the regulation is eittreinelffine and that-the loss of e'nrgvin the regulating a'ppaiatus is'rcduce'd to a n'iinimum.

.In systems in which carbon piles have been used it is Wit-jitillltllf) to provide an electr'omagnet near the pile for' operating the. same, which magnet isfopposed by the action ot a spring or some similar means. In such systems. regardless of the value of thetwo opposing forces, the only force available for vaijying the pressure of" the" carbon pile is' the unbalanced cmn fionent l)l'ttl()lll]ll2\tlllg either 11] the spring .01 magnet and. with a slight voltage variation this component of force ts f 'erysma ll In con;-

parison with the .t'iio forces acting upon the pile. This causes the regulation to hepoor and an 5 excessive amount of energy to be used'inthe regulating! apparat-us.. Also.- in previous a rrangg'elncntsof this ltind, as the magnet windings are nti'naoasly in oil'- cu-it. thou-become consideifgibly heated and the resitltin'gt increase in ten'i' ')crat-ure in the i windings alters their re stance and 111- itl1'ltHtHl 'tl ifect-s the regulation. If the magnet: windings are'infclose proximity-to the blocks ot'thc ca1'bo1t "'p1le, as s customary. j the heat may also afttect these td-etrnnentally. ltlso as parts of the regulating apparatus are normally in a condition of equilibrium vibrations are apt to also inj u-.

riouslv atlect the l'tg'ltltti lflllr particularl with conditions of high lmttery ioltagre and low lamp load. it a dash-pot is used to eliminate these disturhances due to \ibra tion the disadvantage a rises that the density tot the liquid varies considerably with temperature changes.

Various objects of my int-"ention are to provide in'ip'rovenients which will obviate these and other disadvantagesoand in so doing I provide a means for locking the apparatus which operates the carbon )ile so that themagnet need not betenergized except when the system is nndergoing regulation. Furt-hermre,-I provide an electro-- magnetwhich is not directly subject to variations in the work circuit voltage but which i:.-: made to operate responsive thereto" by means of an auxiliary electro-responsive device which throws such magnet into operation when it is desired to operate it responsively to variations in voltage on the work circuit. I

My intention further-includesautomatic means for operating the loclgi ng device and means for clamping the action of the operating. mechanism so that it. will Work smoothl} and efficiently. I v

Various other objects. features and advantages will more clearly amiearafrom the detailed description given below taken in connection with the accompanying,(l-rawing which forms a part of this specification and bodying one "form of, my 1.) 'ovenients.

In the drawing, 1 represents a main generator feeding the circuit 2, 2; Connected across the circuit- 2. 2 is" a storage hatter 2} which is designed to be charged from the enerator l and to feed the circuit 2 wheii the generator 1 is not in operatiotn --l. -l indicates a work or consumption circuit which may include lann'isfl or other translating tle i'ce s andwhich isfedor sup plied hr the szenerator lor batteryfi tlu'ough the circuit. 9. 2. The bfliitdrl') Ratnd generator inventionand imelectromotireforce. sinetywhen the grind; ator is operating and the battery is elm-re;- ing' therefrom the voltage applied to the circuit 2.2 is somewhat greaierthan when the generator is inope-ratiye and the. battery is supplying; said circuit. 1

In order to maintain the iohagg-racross the main circuit i. 4 sul'istantiallj' constant T place in the circuit 2; between the batt er E5 and the work circuit 4. t a variable resi t- :"ance. For" this" Yariaide. resistance l n-( tcral,|l use a pile ot carhon liloclt's aswhich showsdiagrainma tical1y a system em- 1 takentogether-tram a source of varial' lctt 'electromagnet 18 is normal-l ,rrates a switch mom or 20. The pull of the a pawl llll d lililiet a rrangemei' t at, its lower .cnd'kv At itslower ehdthe l'eyer 6" carries a 'volve but its speed is kept .down because shown. the resistance of which is varied by variations in pressure exerted thereupon by a lei'e'rfi piroted-at the oint 7. The lever (i carries a piroted mem )er- 8 for cn 'aging with one end of the pile of carbon blocks. The lever 6 is controlled by means of a coil in the form of a solenoid-.9 which operates upon a: core 10 )ivota-lly connected to the lever i at 11. Tie-core) is aiv-oted at its other end to a link 12 wl-iic1 in turn is pivotally mounted to the framework at 13 When the solenoid flisenergizejd this tends to attract the corelO. m-oring it to the left to cause the lever 'o'r'a rm G to mmpress-the pile of carbon blocks The action or the solenoid 9 is op 'iused' by a; spring 14, which may be adjusted by means of screw 15 and nuts 16 situated on frame piece 17.

Oonnected'ydireetly across the work circuit 4, 4 is a c-oil of an electromagnet 18. This coil is thusnia-de responsive; to variations in the voltage of the consumption or work circuit 4. The el'ectromagnet is arranged to operate 11' on a core 19 which opbal'anced by means of a weight 21 secur to the switch member 20 on the opposite side of'its fulcrum 22 from that on which a core-19 is situated. When the yol tage on the workcircuitdrops the pull-on the electromag'net 18 is decreased, ,thus allowing the swltch 20 to contact with the terminal, 23, so that .the solenoid 9 is connected in circuit across the main line. This circuit maybe traced as follows: conductor 24 connecting with the; switch member or arm 20 at point 25, contact terminal 23, conductor 26', solenoid 9, conductor 27', magnet coil 28 and; conductor 29. This current: passing throu' h the solenoid 9 energizes the same so t'at itexerts a. pull upon the core 10 to cause the lever (l-to compress the pile of carbon-blocks 5 so that the resistance in the circuit 2 between the source and work circuit is decreased, thus "allowing the voltage at the workcircuit to be increased and brought back substantially as its original or normal 'l' heaction ofthe lever. 6 and its cooperating mec' anifs'in is dampen-ed by 'm eans of toothed" "rent EB-i hicl n-gagjes'with a engaged pe dulum 3 e'verb the ratchet a. w i t W-Eiill is. exerted on the weal; 31 ismafde to reof the pawl'andpendnlnn'i 3 2, 33'. During this action the pawl" 32 and pendulum are held in :r

length of the end-ulum and the weight thereon. In or er to lock the lever 6 and its appurtenant mechanism against operation it is only necessary therefore to lock the ratchet wheel 31 against revolution. To do this I pivotally mount the pawl upon a member 34 which in turn is pivotally mounted to the main frame at 35. 1. 0s ring 36 acts upon an arm 37 which is fixed y secured to the member 3a and which normally tends to force the pawl 32 in thorough engagement with the teeth of the ratchet wheel 1-11 to lock the same against movement. Thus normally, the lever 6 and its appur tenant mechanism are locked against moxiement.

attract its armature or member 34 'so that the pawl 32 will be retracted to a position such that whentaken in connection with the ratchet wheel 31 it will act as an, ordinary escapementand will dampen the action oftxe lever 6 and consequently the ance f. \Vhen, therefore, the solenoid 9'is. energized to compress the carbon pile rsista-nce 5, as, above explained, the magnet 28 is energized at the sammtimeyto. attract.

From the above it willbe evident that. l. have provided. a system and improvements in rcgulating appa 'atu-s thereforwhich rendcr thc same economical and efficient in opt-nation and coi'istruction and more ctl'eotivc for the purposes described. The various disadvantages of prior systems above pointcd out are substantially eliminated and a regulating apparatus produced which has many new and useful fcatures and improvements as applied to one specific form ofments.

Although I have shown my unprovesystem and in one particular form of apparatus it will be evident that there are many other forms and many arrangements of circuits and apparatus to which my invention and in'iprovements may be applied.
